(L) [2006/05/20] [Ho Ho] [Elephants dream] Wayback!As you all probably know, the first Open Source movie was released some time ago. Today it had a web release. That means you can download the full movie and all the data that was used for creating it from web free of charge. Everything should be released under Creative Commons license.

I haven't yet checked but I think there should be plenty of nice datasets for tracing [SMILEY Smile]

(L) [2006/05/20] [lycium] [Elephants dream] Wayback!that indeed does look like a pretty good quality dataset for renderer development! i'd be interested to know what kind of rendertimes they had for a full 1920x1080 frame (like [LINK http://upload.wikimedia.org/wikipedia/commons/d/dd/Elephants_Dream_Emo_and_Proog.jpg]), along with what kind of shaders/brdfs and lights they use. thanks for the link ho ho!
in the wikipedia article about it they mention that hair and fur algorithms were developed especially for this movie, which leads me to wonder whether it's more efficient to represent such geometry implicitly or tesselate it into triangles. in the latter case, since the density shouldn't vary too much, grids would probably be a pretty good solution (given memory constraints), but trading flops for memory access seems like a better idea.
gaaah, writing a professional rendering system is so difficult :/
